The best thespians use their voices as instruments to convey every feeling ranging from angry to Zen.But what about Deaf actors who, because of their use of a visual language, have less access to performance art than their hearing counterparts? Some people might suggest that they are lesser actors because their powers of expression are diminished.Those people have never been to a Seeing Voices Montreal (SVM) rehearsal in which Deaf actors performing side by side with hearing colleagues, bring words to life using their hands, bodies and facial expressions.
